Multi-element biological alga fertilizer for preventing and treating rice spike develop abnormality, and preparation method thereof

Abstract

The invention discloses a multi-element biological alga fertilizer for preventing and treating rice spike develop abnormality, and a preparation method thereof, and belongs to the technical field of special fertilizers for rice. The fertilizer comprises, by weight, 10-50 parts of alga powder, 2-15 parts of compound sodium nitrophenolate, 150-450 parts of urea, 150-450 parts of potassium sulfate, 100-400 parts of monoammonium phosphate, 50-250 parts of calcium magnesium phosphate, 0-50 parts of calcium silicate, 2-15 parts of EDTA chelated zinc, 2-15 parts of EDTA chelated boron, and 15-40 parts of a microbiological agent. Compared with fertilizers in the prior art, the fertilizer of the invention is natural and green, has no pollution, can effectively prevent and treat the rice spike develop abnormality, can promote the rice spike chaff closing due to the addition of medium trace elements of calcium, magnesium, sulfur, silicon, zinc and boron, improves the stress resistance of crops and the fertilizer utilization rate, improves soil, cultures fertility and improves the quality of the crops.

Description

technical field [0001] The invention belongs to the technical field of special fertilizers for rice, and in particular relates to a multi-element biological seaweed fertilizer for preventing and treating unclosed rice hulls and a preparation method thereof. Background technique [0002] Rice is the largest food crop in my country, with the largest perennial planting area (30 million hectares), accounting for about 30% of the country's grain, the highest yield per unit area, higher than the national average grain output of more than 10%, and the highest total output (about 30% of the country's grain 40%), the largest consumption, the domestic trade market is small, rice production and consumption can only rely on domestic self-sufficiency. [0003] Since 2004, cracking and deformation of rice glumes have occurred in many places in the Huaihe River Basin of Anhui, and the phenomenon continues to increase; it has also been reported in Shiling, Suqian, Huangli, Xiangzhou, Guangxi...

AI Technical Summary

Problems solved by technology

Cytological studies have shown that the application of multivariate fertilizers to plants will produce antagonistic effects, which is not conducive to the absorption of fertilizers by plants. When the concentration is high, plants will suffer instead.
